Are you planning a new construction or would you like to renovate your roof or façade? You can rely on aluminium. The reasons are obvious:
LIGHT & AFFORDABLE
The weight of an aluminium roof is about 1/10th to 1/20th of that of a tiled roof. With a dead weight of just 2.3 to 2.6 kg/m², an aluminium roof covering is particularly lightweight — and can be mounted on virtually any roof pitch (exceeding 3°). The advantage: in most cases, older roof structures do not require extra reinforcement. That often saves a good deal of money. Our tip for restorers: take it easy.GO TO THE RENOVATION GALLERY
MADE TO LAST A LIFE TIME
Aluminium reacts with oxygen in the air to form a natural oxide layer. This layer offers outstanding protection from corrosion (including bitumen corrosion).
A damaged roof or façade membrane made from aluminium will always regenerate itself. The aluminium supports are also protected by a two-layer stove enamel finish. So you can enjoy your roof for years — and the next generation can too.
Thanks to the concealed fasteners and installation in a half-offset pattern, a PREFA roof can resist even the harshest of weather. In high-risk regions, storm-proofing can be further improved with additional clips.
Our PREFA roof is reliable on mountain huts too. On boiling hot days and freezing cold nights, it’s not uncommon for maximum and minimum daily temperatures to differ by 50 °C. That’s not a problem for a PREFA roof!
From an ecological point of view, aluminium is the ideal choice of material. There are various reasons for this::
! Aluminium is fully recyclable.
! During recycling, only 5% of the original energy used for production is required.
! PREFA generally uses secondary aluminium (= recycled aluminium).
! As aluminium is so lightweight, energy is saved and CO₂ emissions are reduced during transport to the building site.
We say it again: aluminium is extremely durable, virtually maintenance-free, recyclable without any loss and unbelievably lightweight. All factors considered, the eco-balance is far better than is the case with traditional roofs.
